BACKGROUND OF THE INVENTION

The present invention relates to the central body portion of a catamaran boat. More specifically to a catamaran central body structure to be attached to as well as carried above water by a port and a starboard hull with both having a weather sheltering roof means.

Catamarans have many characteristics that make them desirable for recreational boaters. Generally, they offer a wider width which provides more deck and cabin space than similar length traditional monohull boats. The more slender hulls of a catamaran boat are more easily driven through the water thus making the catamaran relatively faster and more economical to operate. In sailing applications, the wider width eliminates the need for a heavy keel, thus faster and more economical, as well as a more stable platform. However, when a catamaran is constructed as a single one-piece module, then the wider width becomes a major problem for towing over land. To overcome this problem, many designs have been proposed which contemplate decoupling the hulls from the central body structure in order to reduce the catamaran's width for towing. The present invention provides a central body structure that can be attached to habitable port and starboard hulls having weather sheltering roof means. The present invention is particularly applicable to a cruising catamaran boat which you want to industrialize the manufacture of and thereby lower the economic cost of a catamaran. Because, thanks to its removable nature, it allows a product industrialization, by dividing a catamaran in three modules of smaller dimensions. The present invention also allows convenient entry as well as communication with interior space in each roof sheltered hull, with hulls of the type having sheltered stand-up room for habitability.

U.S. Pat. No. 6,640,737 issued to William S. Chacon discloses a multi-hulled watercraft wherein each hull swing retracts under a central cabin structure by the said hull outboard side swinging from a row of pivot hinges located close to roof on two opposing sides of said cabin structure and said hull inboard side is guided to roll or slide on a track system that is attached endwise to an outer surrounding frame under said cabin structure. The present invention differs from this invention because the present invention does not require a said central cabin underside track system that is attached endwise to a said outer surrounding frame to roll or slide on. The present invention also differs in that a pair of habitable hulls having weather sheltering roof means are enabled to be together (hull and roof) attached to or detached from hull-wise associated said flange lips inboard and/or outboard side as also roof-wise associated said side walls inboard and/or outboard side forming a variable width catamaran boat. The present invention further differs in that the present invention is of the central body portion only and not of the entire catamaran watercraft (boat).
